离线安装docker
https://download.docker.com/linux/static/stable/x86_64/ 下载离线包地址
1）setup
cd /usr/local/resource/docker tar -xvf docker-19.03.4.tgz mv docker/* /usr/bin/ # 将二进制文件移动到bin下
2）systemd docker.service
vim /etc/systemd/system/docker.service
然后将以下内容粘贴进去：
[Unit] Description=Docker Application Container Engine Documentation=https://docs.docker.com After=network-online.target firewalld.service Wants=network-online.target [Service] Type=notify # the default is not to use systemd for cgroups because the delegate issues still # exists and systemd currently does not support the cgroup feature set required # for containers run by docker ExecStart=/usr/bin/dockerd -H tcp://0.0.0.0:2375 -H unix://var/run/docker.sock ExecReload=/bin/kill -s HUP $MAINPID # Having non-zero Limit*s causes performance problems due to accounting overhead # in the kernel. We recommend using cgroups to do container-local accounting. LimitNOFILE=infinity LimitNPROC=infinity LimitCORE=infinity # Uncomment TasksMax if your systemd version supports it. # Only systemd 226 and above support this version. #TasksMax=infinity TimeoutStartSec=0 # set delegate yes so that systemd does not reset the cgroups of docker containers Delegate=yes # kill only the docker process, not all processes in the cgroup KillMode=process # restart the docker process if it exits prematurely Restart=on-failure StartLimitBurst=3 StartLimitInterval=60s [Install] WantedBy=multi-user.target
授予执行权限：
chmod +x /etc/systemd/system/docker.service
然后：
systemctl daemon-reload systemctl start docker systemctl enable docker.service
测试是否成功：
systemctl status docker docker -v
